Abstract

Deep Underground Neutrino Experiment DUNE INSTRUMENTATION RELATED TO NUCLEAR SCIENCE AND TECHNOLOGY near detector neutrino PHYSICS OF ELEMENTARY PARTICLES AND FIELDS
The Module-0 Demonstrator is a single-phase 600 kg liquid argon time projection chamber operated as a prototype for the DUNE liquid argon near detector. Based on the ArgonCube design concept, Module-0 features a novel 80k-channel pixelated charge readout and advanced high-coverage photon detection system. In this paper, we present an analysis of an eight-day data set consisting of 25 million cosmic ray events collected in the spring of 2021. We use this sample to demonstrate the imaging performance of the charge and light readout systems as well as the signal correlations between the two. We also report argon purity and detector uniformity measurements and provide comparisons to detector simulations.
